A 27 yr old female presented to the Urology department, Institute of kidney disease and research centre, Ahmedabad, Gujarat, in April, 2014 with bilateral dull aching flank pain, more on left side, early satiety, incapacitating her day-to-day activities for the last two months. She was on antiepileptic drugs for her convulsive episodes since early childhood. Examination revealed protuberant abdomen with multinodular, smooth, firm swellings and multiple adenoma sebaceum on her face ([Figure 1]). Her biochemical investigations were within normal range, with serum creatinine-0.8 mg/dl. Contrast enhanced CT-abdomen revealed huge heterogeneously enhancing mass lesions with fat density (negative hounsfield units) in both the kidneys, left kidney measuring 26x19x10.5cm, with barely visible renal parenchyma. Magnetic resonance imaging (MRI) brain showed cortical tubers in cerebrum and subependymal nodules in foramen of monro ([Figure 2]). The patient underwent retroperitoneal laparoscopic control of renal artery followed by left open nephrectomy via flank retroperitoneal incision. Grossly, left kidney was totally distorted and replaced by multilobulated mass with no visible parenchyma and light microscopy on hematoxylin and eosin (H&E) staining revealed combination of mature adipose tissue, bundles of smooth muscle and abnormal blood vessels, suggestive of angiomyolipoma ([Figure 3]). Presently, she is asymptomatic and her nadir serum creatinine was 1.1 mg/dl at six month follow up.
